Android pass value Activity

I want to pass a value from the ListView Activity 1 Activity 2 for editing.

I have this code but the value is not passed in the second Activity.

ACTIVITY A

Intent i = new Intent(this, Modifica_entrate.class);      
Bundle extras = new Bundle();
extras.putString (tv1.getText().toString(), data);
i.putExtras(extras);

ACTIVITY B

Bundle extras = getIntent().getExtras(); 
String valuePass = extras.getString("data");
mDataScelta.setText(i.getExtras().getString(valuePass));

You are mixing up keys and values a bit too much.

The first parameter here:

extras.putString (tv1.getText().toString(), data);

Must match the parameter here:

String valuePass = extras.getString("data");

So the code you have there puts a String with the key tv1.getText().toString() that is, it takes the text you entered in the textbox and uses it as a key (which is probably not what you intended to do). For this key, you are putting the value of the variable data. Then you try to retrieve the key "data" (note also that data and "data" are not the same thing).

So what you want is probably:

extras.putString("data", tv1.getText().toString());

And then you can retrieve it like this:

mDataScelta.setText(i.getStringExtra("data"));
